I thought it was the mgm fire in 1980.Ever since that big hotel fire years ago, Las Vegas has gotten as paranoid as Chicago. I was looking for some Class 1, 18 Ga audio wiring (either AC or MC) and because I didn't want to run pipe. My first thought was to see if the manufacturers made anything special for Las Vegas.
All it had to be was two 18 Ga TFFN, red and black listed type AC. I know they will make anything but custom comes with a minimum. I didn't need 100K feet. That's why I was looking for off the shelf. They do have FA MC cable with 18 GA conductors but that is painted red. Couldn't use red and without the paint is a custom. So I ran EMT and pulled TFFN that I had twisted up and put on a 2000 ft reel. (Can't remember by whom.)I thought it was the mgm fire in 1980.
For various MC low voltage cable if you need something non standard AFC will apply armor to customer supplied wire/cable
